Where to buy?

Hey guys, my computer is about 6-7 years old and I may start looking to get a new one soon as within the last year it's begun to turn itself off randomly.

Any input on where the best place to get a desktop from? Not looking to get a high-end "gaming PC" per se, but maybe mid-level or a decently powerful computer that could play most games.

It's been a long time since I got one and obviously times are different now, especially with going into stores, so should I just look on Amazon? Not looking to break the bank on one.

I actually got my last PC through eBay, from a computer store that builds gaming PCs and sells through the platform. It was cheaper than sourcing all the parts myself, and a time-saver. They're only in Australia, but I imagine there'd be similar sellers on eBay US that offer that service. That might be an alternative to Amazon or a chain retailer.

Do you have a MicroCenter near where you live?
